(Cl. 308-138) 7 YThe invention relatesto :a side bearing for 4use with railway vehicles and more particularlyto a resilient type thereof.

An object of the present invention is to provide a side bearing capableof cushioning or snubbing the rocker -roll of a railway car body.

, Another object of the invention is the provision of resilient means ofdifferent character in a-side bearing to resist the compressive movementthereof as well as return a compressed side bearing toexpanded or normalposition.

A further object of the invention is the provision of resilient means ina side bearing to resiliently resist a downward and horizontal movementof a portion of the side bearing.

A still further object of the invention is vide a vertically adjustableside bearing which is adapted to be interposed between spaced members ofla railwayvehicle. -f-

An additional object of the invention is to provide, in a side bearingunit, a resilient means interposed between two relatively movablemembersV thereof and resilient means of. different character actingbetween the movable members to ensure a completely expansive movementof'a compressed side bearing as well as preventharmonic action of theresilient means of the unit. The above and other objects Awill becomeapparent from the succeeding description ofan ex'- einplied form of theinvention which istillus.- trated in the' accompanying drawings andwherein: v v l Figure `1 is a horizontal View of a side bearingembodying a form `of the invention, a portion thereof being shown insection and the remaining k portion thereof being shown in plan. y

Referring now in detailto the drawings, wherein like referencecharacters designate like parts,

and Viirst considering theI embodiment of the invention illustrated-inFigures lto, 4, inclusive,

the numeral Igenerally indicates a' sideb'e'aring of the abovereferredto resilient type adapted to be supported by a` bolster or loadcarrying member of a railway vehicle truck., only a top surface 2 ofwhich is shown. lThe side Vbearing comprises a sleeveor retaining meansv3 havingabase i. n plate- 4 bearing, upon the-truclrbolster andbetoproing suitably apertured tolacommodate rivets or any desired typeof meansfor securing the sleeve to the bolster and thereby4 retain it ina predetermined position. Upstanding from the base plateA are centrallydisposed, laterally spaced, longitudinally extending side walls 5 joinedby or merging into arcuate or cylindrically formed end walls 6 topresent an upwardly` opening relatively shallow receptacle vl.v y

Occupying thereceptacle and prevented. from shifting in any. horizontaldirectionrelatively to the ysleeve by means ofthe sidey and end wallsthereof is a housing or casing 8 comprising a bot- -tom or lower platemember 9 having upstanding therefrom in longitudinallyv spaced relationra pair,.or a plurality, of upwardly opening, cupshaped, tubular orcylindrical members lll. Transversely spaced side ribs Ilv anda centralriblZV extend between and integrallyY join the v.cylindrical members torigidify the housing against stresses to which it `will besubjecteddur,- ing service. Since the side bearing engaging surface of the bodybolster, indicated by the diagrammatic line I3, may, dueto manufacturing`tolerances in the respectivek bolsters, vary in height from the opposedtruck bolster surface 2, and the present side bearing is arranged andconstructed to be, at al1 times, against or to be "in constant contactwith the body bolster surface I3, the side bearing is desirably made.adjustable vertically in order to be capable of being interposedbetween opposing bolster" surfaces and perform the function for which itis designed. AFor the accomplishment of this purpose-there is provided aplurality of shims or plates I4, the exact number and thickness of whichis to be determined upon an application of a side bearing 1 to a railwayvehicle. The shims are in subjacent `relation to the housing bottomplate 9 to main- "tain the housing and its associated structure inioning or snubbing theVV roll or rock cfa vehicle car box. The sidebearing, positioned adjacent l anextremity of aload carrying member ortruck' bolster, only a top surfaceZvj of which is-'illustrated,comprises va sleeve or retainingmeans 3a having a base plate lla bearingupon the underlying bolster and being suitably apertured for theaccommodation of 'holding' meansY of any desired nature for retainingthe sleeve in a predetermined position. Projecting upwardly from thebase plate,vv substantially centrally thereof, are transversely spaced,longitudinally extending, side walls 5a terminating in or merging intolongitudinally spaced, cyindrically formed end walls 6a to tacle la.

' Positioned Within the receptacle is a housing- `lar members aretransversely spaced side ribs Ila of bulged or arcuate configuration,when viewed from the top, which rigidify the housing against stressestowhich it will be subjected during service.v The side ribs, together withthe included portion ofthe associated cylindrical members, presentanupwardly opening chamber Yor compartment 32,A the purpose l of whichwill be hereinafterexplained. I

As set forth in the previously described embodiment, the height ordistance of a Vvehicle e body bolster, only a lower surface thereofbeing A indicated by the diagrammatic line f l3i,l from the underlyingtruck bolster surface v2a may vary due to manufacturing tolerances, andsince the present side bearingis designed to constantly bear against thebolster surfaces, with `consideration being given to al predeterminedcompressive movement of the side bearing, it becomes necessary toprovide for a vertical adjustability of the housing and its associatedparts. To fulll this purpose, therefore,` a plurality of shims or llerplatesl illa are housed by the represent a relatively shallowhrecep-`The housing comprises a bottom or bedv 2,32954` the side bearing,generally designated as la, is also `of the resilient type and 4 capableof cushceptacle 'la and interposed between the truck l bolster surface2a and the housing bottom plate 9a. The shims may be of any thicknessand quantity, as the condition requires, in order to maintain lthehousing in a predetermined elevated position. y l

Like the previously described embodiment, no additional means isrequired to prevent an accidental or unwarranted displacement of thehousing from the illustrated p0sition, `but as `a precautionary measureand to prevent separation of the housing and sleeve during shipment, theportion of each cylinder -adjacent the sleeve end wall and the lowerextremityof the housing is provided with a transversely extending reliefor indent 33. In substantial alignment with each housing indent arelapertures 3Min each` sleeve end wall, being*` of a height less thanthat of the corresponding relief. Extending through .the -apertures andpositioned in the relief is a ybar or locking member 35which is, afterapplication to the side bearing, bent channel-shapedto' prevent movementthereof in a longitudinal direction. Eachrelief extendsabove and belowthe 'associated bar soth-at the housing maybe raised or lowered from theillustrated-'position as required. e

Forming vthe top or'body bolster contacting memberv of the side bearingis a movable cap or cover i8a which is formed, in part, by an upper orbearing pl-ate I9a arranged to present an appreciable area forengagement with the surface I3a of the body'bolster. The bearing plateis positioned a desired distance above the housing, which distanceisdeterminative of the downward movementof the cap or compressivemovement of the side bearing. vThe 'cap' bearing plate has,r adjacentlits periphery, a depending flange 29a overlapping the upper extremityofthe housing to'form a shield whereby foreign substance is preventedfrom entering the housing. The flange is spaced a predetermined distanceaway from the housing so that it will not engage the housing during adownward movement of the cap to `build up additional forces in the sidebearing.

'Positionedwithin each cylinder is a resilient member 2lia formed, inthe instant case, of a deformable material such as a-rubber 'compoundand being adapted to resiliently resistl'a compressive movement of theside bearing. So as not to arrest the flow of material upon theapplication of compressive forces" thereto, each resilientl member issuperimposed -upon an upwardly directed convolutionf'Zla formed in thehousing bottom plate-and disposed centrally of the associated cylinder,thereby presenting lower pockets for the reception of the displacedmaterial;r Likewiseg-the cap bearing plate is provided with downwardlyfacing, circular abutments or shoulders 22a disposed oppositely from theconvolutions and bearing' uponthe upper extremitiesof the resilientmembers 29a.

The resilient members are desirably annular, cylindrical or tubularinformation to contain axial bores 23a for the accommodation of prongs,arms or depending members 24a which formcontinuations of the capshoulders. since the prongs are in intimate Contact with the resilientmembers, the arrangement forms a means whereby the cap may becentralized and also a movement of the cap horizontally either in atransverse or a longitudinal direction will be resiliently resisted. yThe resilient members, before assembly with the housing and cap, arepreferably of an outside diameter less than' the inside diameter of theoccupied cylindrical members Illa, and the bores 23a are of a diametergreater than the diameter of the associated prongs so that the housing,cap and resilient members may be easily assembled. Upon depressing thecap to the illustrated position, the resilient members will be initiallyenergized to provide a side bearing of desired capacity. The sidebearing is illustrated with the component elements thereof in normalpositionrwith `the cap capable of moving upwardly away from the housingas the bolster surfacesl move away from one another or downwardly towardthe'housing during a compressive movement of the side bearing.

Assisting the resilient `members in resisting the 'compressive movementof the side bearing and returning a depressed cap to its elevated orillustrated position are a plurality of resilient means of acharacteristic diierent from the rubber members,v and by thisarrangement a harmonic spring action in the side bearing is avoided.
